The Apache server on one of my box crashed last night and the log file simply states:
[Fri Mar 09 23:51:49 2007] [notice] caught SIGTERM, shutting down
One thing puzzled me is that there are a couple of symbolic links created in Apache home directory:
lrwxrwxrwx 1 root root 25 Mar 9 23:51 build;45f23959 -> ../../usr/lib/httpd/build
lrwxrwxrwx 1 root root 19 Mar 9 23:51 logs;45f23959 -> ../../var/log/httpd
They were created around the same time when Apached stopped.
Has anyone seen similar things like this? What could be the root cause?

We have an ongoing problem with Plesk on 1and1 dedicated servers.We host around 80 websites, all of which are very light and have relatively low traffic. When we get to setting up around the 70th website and create a new sub-domain, Apache crashes with the error:
Template_Exception: Can not restart web server:
file: /usr/local/psa/admin/plib/Service/Driver/Web/Server/Apache.php
line: 104
code: 0
We then run "bootstrapper.sh repair" to get Apache back online. But can't create any new sub domains, without the same issue occuring. With each server, 1and1 raise a ticket with Parallels, who log in and fix the issue. But then Following the Parallels fix, the server runs slowly, sometime throwing up 502 errors etc, which nobody is able to fix, and again, we have to move servers.We have just hit exactly the same issue on our 3rd and final 1and1 server.

I have in my possession a new server which is running cPanel. For some unknown reason it keeps crashing about every 4-6 hours where I must get a remote reboot done.
Its starting to annoy me that I'm unable connect to anything. What I suspect is high disk red/write. As what I'm finding is over 10k blocks being written per second with only 300 being read per second. I also am not seeing any bandwidth out/in usage being high.

I have a dedicated server with NyNOC and earlier on today the server dissapeared off the net, wouldn't respond to ssh, http etc, nor pings
I submitted a ticket and the server got rebooted, went through the FSCK check and came back up ok, but now I'm concerned as to what caused it
Andy the technician said he couldn't find out the reason why and neither can I
I can only put it down to PERHAPS faulty hardware somewhere?
The /var/log/messages file doesn't say anything useful, the last entries show..

I reboot my cpanel server twice last night and it had crash
I am now running e2fsck and it's trying to fix the inode thing.. i've been pressing <y> 10000 times! Poor thing my fingers cramp
I've been thinking to mount my primary drive into another cpanel server (not a fresh server) as secondary drive and restore from there. The question is how? I need detailed steps by steps as it's urgent for me..

I just got a new server the other day, installed cpanel and all my usual stuff in it.
Then I started transferring some accounts off my other server on the same network. It would transfer small accounts ok but I have this one big account,. the sql is like 300 mb. It would get to the restore on it then the server would crash and be totally unresponsive.
It has to be manually rebooted at the datacenter. There is nothing in any logs. At first I thought it was the load getting hi and doing it but I ran the unix bench and got the load to 14 and it didnt hurt it.
It only does this on restoring big sql db. At the dc they say the screen on the console goes blank.
Ive done looked and cant find anything in the box. Its actually the same exact setup I use for my other servers.
So the dc is looking at it today. Has anyone ever ran into a problem like this and if so what was the cause?

No one could have missed that there was a DDoS attack on the DNS root servers last week. It’s been all over the news. It seems that aside from the G node (ironically the US Department of Defense) the rest of the nodes did ok (especially since anycast spreads out requests for 6 of the 13 root servers to over a 100 other locations).
In other words, the DNS root servers seem pretty impossible to take down (which is a good thing!)
But...
What would it take to bring down the DNS root servers? What weak links are there?
It would be interesting to have a discussion around this.

I run a web counter/tracking service on a dedicated server with 2x SATA discs (RAID1). There are about 100 MySQL queries per second, most of them are served from RAM cache, about 10-20 per second are inserts directly to disc.
My question: is it possible that this load physically damages the discs over time so that the disk crashes sooner or later?

I've a question, one of the dedicated servers with CentOS and Plesk 8.1.1 crashed. Critical system files were corrupted so it was impossible to start the server.
What we could do is backup;
/var/www/vhost/*.*
/var/lib/mysql/*.*
We installed a new server with same software (CentOS and Plesk 8.1.1), we placed the backupped directories back, restored the MySql database...
But how can we restore the settings? With putty / commandline we can open all restored databases. But we have a feeling that the PSA database is not connected with the Plesk admin (GUI)...
Our primary question, how do we get our settings back in Plesk (like accounts; clients, domains, dns-records and so on?)

I have a lynix root server with 1and1.com and recently the server has been going down I have no access to FTP/the sites or root. Their support tells me to look in var/log but im not sure what file to look in or what im looking for as far as to why the server would crash.
So far my solution has been to re boot the server and it has been working but i need to find the cause of this...any suggestions on where to look or what to look for?

Nothing lags.

Swap isnt used at all.
Should I be afraid of server crash incase server load goes up to 60 or 80 without ram and cpu usage rising that much?

I have a Linux server running some reasonable setups:
Opteron 180, 4 GB RAM, running 8x 36gb 15k scsi with hardware raid 10 -- this is one of the servers from WebNX advertised here not long ago
Running CentOS 4(?), Apache2/MySql 4/PHP5.2, the normal stuff.
I have only one main site on the server, which runs a pretty old PostNuke CMS in Chinese (0.7.2.3 Phoenix) + PNphpBB2 + Gallery 1.5.7 (all integrated into PostNuke). This site is pretty light in "human" traffic, getting about 20K hits per day.
Now, the problem I have noticed with this site, is related to the many MP3 files stored in the Gallery albums. There are lots of HTTP requests to these files, most maybe from Chinese search engine bots (judging from IP), that slows the server to a crawl and even crashes Apache. This happens in the late hours here when it's day time in China. As a matter of fact I just did a reboot, and in 5 minutes there are more than 1000 HTTP requests to MP3 files resulting in a traffic of 2.1+ Gb. So within minutes, the server is brought to its knees again and I can't even get the "apache status" from CPanel now: "Unable to retrieve apache status".
The company that manages the server for me said there's no security problem here. We have installed an Apache extension to limit the number of simultaneous requests to media files to 1. However that doesn't seem to help.

for months my server has been running fine, since about a week ago the server crashed and was up and down
the fault was found to be faulty ram which has been replaced.
now I have had every tom, dick & harry take a look at the server to get it stable again but im still having issues.
The server seems to run fine but crashes when I try and repair or backup my database.
the database is large like 30gig but the server used to do this fine before but it wont now, it get so far then hangs.
Server:
Dual Core Xeon
4GB Ram
2x 250GB HDD

The company I work for unfortunately runs their site on a IIS server. I want to install some forum software, vBulletin or phpBB onto the server and run it on the same site. PHP of course needs to be installed to do this.
Boss is worried that putting PHP on same server as ASP might take down the site if something goes wrong. What are the odds of this happening if I follow directions and what steps should I take to install?
